Why the Title Document Decides Everything
When buying property in Thailand, the title document is the single most important factor. It determines what rights you are actually acquiring – and what you are not. Unlike many Western countries, Thailand has different levels of property rights, and not every document offers the same protection. If you are not careful, you may end up buying less than you think.
The Four Title Documents
Thailand recognises four types of title documents, which differ significantly in terms of legal security.
Chanote (Nor Sor 4 Jor)
The gold standard. A Chanote is a full title deed with GPS-surveyed land boundaries, registered at the Land Department. It offers the highest level of legal security and is the only title type that can be sold, mortgaged or encumbered without restriction. When buying property in Thailand, you should always insist on a Chanote.
Nor Sor 3 Gor
Also offers good security. The land has been surveyed and mapped by the Land Department – though based on aerial photography rather than GPS precision. A Nor Sor 3 Gor can be sold and transferred without a 30-day public notice requirement, and it can be upgraded to a Chanote. In practice, it is acceptable for most transactions – however, it is not a full title deed in the strict legal sense.
Nor Sor 3
Grants a right of possession and use, but not full ownership. The boundaries have not been precisely surveyed, which can lead to boundary disputes. Any sale or transfer requires a 30-day public notice period, giving third parties the opportunity to raise objections. With the appropriate land survey process, a Nor Sor 3 can first be upgraded to a Nor Sor 3 Gor and then to a Chanote.
Sor Kor 1
Merely a notification of possession – evidence that someone is using the land. It is not proof of ownership and cannot be sold or encumbered with registered rights. No new Sor Kor 1 documents have been issued since 1972. Upgrading to a Chanote is today only possible through a lengthy court procedure – with an uncertain outcome. Avoid any property that comes with a Sor Kor 1.
Freehold vs. Leasehold
Freehold means full ownership – the property is in your name, for an unlimited period, inheritable and freely transferable. For foreigners, freehold is only possible for condominiums. The so-called 49% rule stipulates that a maximum of 49% of the total sellable area of a development may be in foreign ownership. Your individual unit belongs to you 100% – the quota applies to the building as a whole, not to your unit. When purchasing freehold, your name is entered directly on the reverse of the Chanote.
Leasehold is a lease agreement – you acquire the right to use the property for a defined period. Thai civil law limits registered leases to a maximum of 30 years. A leasehold registered at the Land Department survives a change of ownership through sale – the new landowner is bound by the registered agreement. The real risks lie elsewhere. First, renewal clauses (30+30+30) are not enforceable following a landmark Thai Supreme Court ruling of March 2025 – every renewal must be renegotiated and re-registered at the end of the current 30-year term. Second, in the event of the lessor's insolvency, a bank foreclosure can put the leasehold at risk if the land was mortgaged. Third, a leasehold automatically terminates upon the death of the lessee – unless the agreement contains an explicit succession clause. Even with such a clause, its enforceability against a new landowner is legally uncertain.
Additional Security Instruments
Experienced buyers combine the leasehold with further legal protections:
Usufruct: A right registered at the Land Department entitling the holder to use the property and derive income from it – either for a defined term or for life. A usufruct survives a change of ownership through sale, which makes it particularly valuable. Important: a usufruct terminates upon the death of the usufruct holder and is not inheritable.
Superficies: The right to own a building on someone else's land. If you build a house on leased land, a superficies right secures your ownership of the building itself – independently of the land. Unlike a usufruct, a superficies right is inheritable.
Right of First Refusal: A right registered at the Land Department giving you the pre-emptive right to purchase the land should the landowner decide to sell.
Which Form of Ownership Is Right for You?
For most foreign buyers, our recommendation is as follows: if you are looking to buy a condominium, freehold is the clear first choice – provided the foreign quota has not yet been exhausted. For houses and villas, a leasehold combined with a usufruct and superficies is the most secure arrangement. Make sure that all rights are registered at the Land Department – an unregistered agreement offers little protection. And always have the leasehold agreement reviewed by an independent lawyer who is familiar with the current Supreme Court rulings.
